Does DPP 4 install along side of 3.14.15 or does it overwrite it? Will the installation make this easy or will it require some custom work? I don't have one of the supported cameras but would like to take a look at it.

I couldn't find the manual on the Canon site and when I started to install it I chickened out before letting it go.

Thanks, Dave

Doh, As soon as I post I found this:

Digital Photo Professional 4.0 and Digital Photo Professional 3.14 can be simultaneously installed to one computer.
